AudioRack Suite supports eight players (by default, configurable for more or less) which can play any QuickTime supported audio file format or play through from an audio input device. The system also supports a single "playlist" which when automation is enabled, is kept filled with either singly scheduled items (inserts) or items from the most recently scheduled playlist rotation. The playlist will automatically load/unload/play the eight players as if a DJ were operating CD players. The system also can perform shoutcast and RSP stream encoding and mp3, wave or aiff file recording from any of its output busses or from an input device. All inputs, outputs and recorders now support AU effect stacks.
